At first please appologies my bad english.
I´m a gold 2 player . I bought Seedorf ( 88) because I tried before Blanc ( 85 ) and Sissoko ( 84 ) and they didn´t feel so agile by far.Then I saw Seedorf mid and I must buy him .I play in the 4-5-1 formation but in the game I always switch into the 4-4-2 formation. I have Seedorf close to Bruno Fernandes Winter refresh as my 2 CM´s. The best chemistrystyle for Seedorf is Shadow , because he will be much faster and a areal beast in the defence.In the game he plays very strong. when he lost the ball he fights to get the ball back . His passes are very precise. His shots are very strong and his longshots are just incredibel. Seedorf is playing very predective , he is simply everywere on the pitch .When you are looking for a fast and a "midelfield beast" and you have enough Coins to buy him, then you are good to go with Seedorf .
stamina depends on the instructions
